From performance to recording and arranging, McCartney said the group found ways to make themselves a little different from the competition

According to ScreenDaily.com, McCartney will lend his voice to Paul McKenzie, a walrus who also happens to be a left-handed bassist, like the Beatles legend himself, and who plays in a band called The Sweets.

The Beatles star has five children, including four from his marriage to his first wife Linda before she died in 1998 from breast cancer
